Abstract
A fluid adsorption system is provided with a waste saving valve interconnecting companion adsorption beds of the system at the inlets for the adsorption beds. A solenoid control is also provided to control the intermittent actuation of the waste saver valve. The control momentarily interrupts the fluid flow of the feed stream toward the beds and actuates the waste saver valve to provide partial pressurization of the depressurized bed by gas flowing from only the inlet end of the companion bed. The pressure equalization occurs quite rapidly and the control then interconnects the feed stream with the second bed so as to initiate the adsorbing process while simultaneously connecting the first bed to a waste fluid exhaust outlet to provide for discharge of the remaining gases therein and regeneration of the first bed.
